Blue Gularis Killifish (Fundulopanchax sjoestedti)
The Blue Gularis Killifish, also known as Blue Lyretail Killifish and Golden Pheasant, is a striking, brightly colored fish that adds a splash of beauty to any aquarium. Males have iridescent blue and red spots on their bodies, while females are more subdued in color.
These fish display a curious and somewhat aggressive personality, growing up to 4-5 inches in length. Due to their territorial nature, it is best to keep Blue Gularis Killifish as a pair or in small groups in a species-only tank. They can be challenging to keep with other fish as they may become aggressive, especially during breeding. To avoid over-harassment, it is best to maintain a small female-to-male ratio, with 2 or 3 females per male in the tank.
Blue Gularis Killifish can coexist with peaceful, larger species that they don't perceive as food. Suitable tankmates include non-aggressive cichlids, larger characins, Corydoras catfish, and Loricariids. Males of this species can be aggressive towards each other, so ample space is necessary if housing multiple males together.
Their diet consists of live or frozen foods such as brine shrimp, daphnia, and bloodworms. Dried foods are accepted only occasionally.
The Blue Gularis Killifish thrives in an environment that closely resembles its natural habitat. Use darker substrate in the tank, along with dense plantings, caves, driftwood, and pieces of wood for hiding and cover. Floating plants will help diffuse the light, creating a more comfortable space for the fish.
A minimum aquarium size of 20 gallons is recommended for a single pair, with 40 gallons or larger ideal for community setups. The water should have a pH of 6.0-7.5, a hardness of 5-15 dGH, and a temperature of 72-77°F (22-25°C).
Keep in mind that these fish are skilled jumpers, so a tight-fitting tank cover is essential.
